There appear to have been a few transmission in the past month with different callsigns. On September 8 2011, a year after UVB-76 changed its callsign to MDZhB, it transmitted a message using another new callsign: 94ZhT. It is unknown yet whether there is any significance to this change.

On the 11th at exactly 1400 UTC, a series of conversations were broadcast between different people on the UVB-76 frequency. It is not yet known where this transmission originated from, although the buzzer can still be heard faintly in the background. Either someone made a mistake, or it’s an unrelated or pirate transmission over UVB-76’s frequency.

There have been a number of transmissions since my last post, in fact too many to summarize here. Buzzer has since stopped, however some counting/unknown beeps have been heard. The beeps are interesting as nothing of that kind has been heard so far.

There hasn’t been much to report on recently. Unfortunately the interest in UVB-76 has waned recently, as the mystery of its silence has died down. It’s believed that the frequency is now being used to transmit messages from another relay.

I’ll update this page when something significant happens. I encourage the readers who actively follow UVB-76 to continue posting updates in the comments (many people visit this page for updates).

For those who ever feel nostalgic about the summer of mystery, there’s always UVB-76 Forever!

Laid at the UVB-76 Internet Repeater has posted an update on recent events. Here’s one section of that post I think is important to note:

“It has been already disputed that UVB-76 may have changed to that callsign permanently […] As far as communication dispatches seem to be built up, the transmission site (and the frequency associated) is a separate entity from the party what actually airs the “content”. Therefore in any moment can someone decide that particular transmission site will now service another “content provider” and so will be. In that context, MDZhB is now simply using the same transmission unit as UVB-76.”

There have been a few transmission in the past couple days. Unfortunately no recordings or transcriptions are currently available. Other than that the buzzer has been operating more or less ceaselessly.

This evening the buzzer stopped, and the carrier signal has also disappeared.

Another transmission yesterday. The transmissions from the so-called MDZhB appear quite frequent with 1-2 transmissions daily. What the connection is with the original UVB-76 – apart from the constant buzzer – is unknown. Perhaps the station has been re-purposed to broadcast these coded messages once a day.

For the enjoyment of everyone who has had the strange pleasure of following UVB-76, I’ve created this experimental track which puts together most of the interesting recent events from the station. Enjoy!

Towards the end it is possible to hear another voice talking in the background. Whether this is from the same transmission is unknown.

Other interesting transmissions, include voices that appear to be answering a phone, now leading to the speculation that UVB-76 is in some way connected to a telephone exchange. Possible if it’s a communications centre. More info on this theory in this post.

There was one other male voice transmission recently, but this is believed to be from pirates.

Feel free to drop by the live chat to discuss UVB-76. Not much happening at the moment as everyone is waiting for the buzz to return. The updates on this page contain all the info that is currently available.

After the better part of another day with no activity – there’s been plenty. First a weak buzzer returned, shortly followed by the appearance of a strong carrier signal. After that it seems like they turned on the power because both the buzzer and subsequent voice transmissions have been extremely loud and clear.

The buzzer stopped briefly twice. Once for a male voice doing a test run of counting, and the second time for a female voice making a full voice transmission. The transmission transcodes to:

82 366 prutjnoi 63 85 99 71

This transmission did not use the callsign UVB-76, but instead “MDZhB” (Rus. МДЖБ), although the transmission was very clearly on 4.625 kHz. The transmissions appear to be genuine from UVB-76/MDZhB.

Some interesting activity over the past few days, some legitimate, some not. Firstly, the UVB-76 temporary internet repeater kit has been upgraded, and it’s now possible to watch a live stream of the WinradHD screen (shows a visual waterfall output of the frequency). Someone is now also recording both the AM and USB feeds into a publicly-accessible archive. Worth checking out if you want a recording of something you heard.

In other news: It appears some pirates have been trying to broadcast over UVB-76’s frequency, and managed to make a message (“XYN”) appear in the waterfall view of the stream (screenshot below – click to enlarge):

Apparently those three letters mean “dick” in Russian. Admittedly this is a cool prank to pull off, however it does detract from everyone’s efforts of following UVB-76. There has also been some “counting” transmissions which were broadcast on UVB-76’s frequency, but may not be genuine.

Aside from that, The Buzzer has been silent. Laid (who runs the live stream) has found a new sine wave being transmitted right next to UVB-76’s frequency. There is currently speculation as to whether this may be related to The Buzzer in some way; possibly as an upgrade/replacement? Follow that discussion here.

Plenty of activity this afternoon. The first piece of interest was a male voice in the background heard saying something along the lines of “these should work, but are very weak” (audio below).

UVB-76 then came back on air and continued the seemingly maintenance-related loop of buzzer-music-buzzer (same as yesterday).

This was interwoven with very clear morse (whether this is directly on UVB-76’s frequency is to be confirmed), and new voice transmissions of at least three people (two male, one female), counting from 1 to 10. Sound clips below.

The third one is most interesting as it’s very clear and contains buzzer, music, morse and counting.

As of this update, we’re still hearing the occasional loop of buzzer-music-buzzer. Just heard one more very distorted male voice counting.

Your embedded media players are refreshing over and over again. I’m unable to hear the recordings for more then a couple seconds.

The audio channel marker (buzzer) of MDZhB (foermer UZB76) stopped on September 9th at 12:35 UTC. Only a blank carrier is transmitted since then.

A new callsign MDZhB (Rus. МДЖБ) showed up. Curently this radio channel is used by two organizations: old UZB76 (rare voice messages) and new MDZhB (daily voice messages). No news at the transmitter site: frequency 4625 kHz, power 10 kW, emission mode R3E (suppressed lower sideband, reduced carrier, full upper sideband), horizontal dipole, station located 40 km Noth-West of Moscow.

In the message of Sept. 16 (15:39 UTC) a second word is PRIORITET = Pavel Roman Ivan Olga Roman Ivan Tatjana Elena Tatjana. Prioritet means priority, it has no meaning per se in this context. Only the full text is a key, it initiates pre-described actions of the recipients.

Hi Jan,

I’ve not yet heard this one (and don’t have a recording). Will confirm and get it up, thanks.

If anyone has recordings, please put them up on Soundcloud.

Hi SJ,

I copied it live on paper. One more voice message was transmitted today at 12:26 UTC: MDZhB 94864 Tritil 6098 1359

Indeed, the channel marker (audio generator producing buzzes) was switched off on September 23rd at 15:48 UTC. However, the same HF station on 4625 kHz (Russian military network Nr 43) is continuously emitting a blank carrier in the R3E mode. Daily voice messages are transmitted with a new MDZhB callsign. The last message of UZB76 was heard on September 10th. This transmission comes from the Moscow region, but the old site near Povarovo has been closed down.
